INNER ranroa SHOES.

Specification of Letters Patent.

Patented Aug. 4, 1914.

To all whom, it may concern:

Be it known that we, ROBERT M. SANDER- sois and CHAUNCY P. WHISLER, citizens of the United States, residing at Akron and Kenmore, respectively, both in the county.of

More especially, the invention contemplates a pad shaped to fit within the heel portion of the foot-wear provided with a shallow concave depression in the upper face of the pad at the point which receives the heel of the wearer, the marginal edge of the pad surrounding the concave portion being outwardly flared or inclined to engage the wall of the heel of the shoe at its upper portion and thereby close the spacebetween the pad and the wall effectually against the entrance of foreign substance and form a snug union therewith to prevent the formation of an opening, the edges of which would tend to irritate the foot of the wearer.

A still further object of the invention is to provide in the concave portion which receives the heel of the wearer a hump or slight projection which supports the central portions of the heel and the 0s calcis bone so that the nerves connecting with these bones are less injuriously affected by the jarring incident to walking on the hard pavements, the recessed portions of the pad around the hump constituting a cushioning receptacle for this purpose.

\Vith the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of parts constituting the invention to be hereinafter specifically described and illustrated in the accompanying drawings which form a part hereof wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the matter hereinafter claimed. I

In the drawings in which similar reference numerals indicate like parts in the different figures, Figure 1, is a longitudinal view of a portion of a boot or shoe with the pad therein; Fig. 2, is a plan view of the pad;fFig. 3, is a sectional view taken on line IX of Fig. 2; and, Fig. 4, is a view taken on line X of Fig. 2.

The pad will ordinarily be constructed of soft vulcanized rubber and embodies a main body ortion 1 tapering from rear to front with t e thin portion 2 under the arch of the foot and with the rear thickened portion 3 afiranged at the heel portion of the boot or 5 0c.

The pad is provided with a marginal edge 4 preferably outwardly inclined at 5 so as to form a slight lip at 6 extending entirely around the pad'to engage the inner face of the wall of the shoe especially when pressure is placed on the pad during its use, that is to say, when the weight of the wearer of the pad rests thereon the tendency is to force the marginal flange 4 laterally against the wall of the shoe to prevent the formation of an opening into which portions of the flesh might enter to thereby irritate and injure the foot.

Within the marginal edge 4 is a shallow concave de ression 7 which constitutes a receptacle or the heel of the foot of the wearer, and preferably arranged centrally thereof is a hump or projection 8 preferably arranged so as to lie under the position normally occupied by the os calcis bone of the human foot and serve as a support therefor,

in doing which the concave .cceptacle 7 is interrupted at this point and surrminds this hump in a horseshoe-shaped fashion. The upper surface of the pad is preferably covered with a layer 9 of fabric to assist the cushioning effect, prevent wear on the hosiery used, and also to act as an insulatin medium between the foot of the wearer and the rubber of the pad.

The under face of the pad is arranged to fit the normally-constructed foot-wear of commerce and the upper face of the pad is fashioned to approximate as nearly as possible the actual shape and contour of the under face of the heel of the average human foot with the projection 8 arranged in such a position as to support those portions of the heel of the wearer which are unsupported by the ordinary foot-wear and thereby relieve the foot from strain and support the os calcis bone from the jar and shock, thereby relieving the nerves connected with this bone from strain which should ordinarily be present were the central portion of the heel of the wearer unsupported.

\Ve claim;

1. In a device of the character described, a pad body having a lower fiat face and lateral faces fashioned to fit within the heel portion of a boot or shoe and having an upper face containing a se1ni-circularly formed depression located in the heel portion of the pad constituting a seat for the marginal portion of the heel of the wearer, and provided with a hump or projection formed by an excess of material arranged approximately centrally of said depression and constituting means for supporting what would otherwise be an unsupported portion of the heel of the wearer.

2. In a device of the character described, a pad body having a lower flat face and lateral faces fashioned .to fit within the heel portion of a boot or shoe and having an upper face containing a semi-circular depression constituting a receptacle for the heel of the wearer and further provided with a hump or projection formed by an excess of material positioned centrally of said depression so as to lie approximately under the heel bones of the normal human foot.

In a device of the character described, a pad body fashioned to fit within the heel portion of a boot or shoe and having a lat eral face upwardly and outwardlydnclined, saidtpad further provided with a semi-circular depression in its upper face comprising a receptacle for the heel of the wearer and a hump or projection formed by an excess of material arranged approximately centrally of said depression and adjacent the rear end thereof and constituting means for normally supporting thennsupported portion of the heel of the wearer.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
